The lab thought of that

When you look at it there is a large warning message like before except this time it says 'Error pressure exceeded limit' you don't understand what that means but you see another message from Jen. 'Yo got a few errors in the log forgot to tell you that when I had you press the button in the lab it recorded it and if you don't press it in a similar way as back then it won't activate it's to prevent people from using your hand to activate it' you sigh a bit in relief and you show your mom the pictures with all 3 of them activated

"Hmm well let me show you something" your mom stands up and motions for you to follow her. She walks into her room with you right behind her and she motions at the twins huddled together asleep on her bed. "Look at how tired they are, if we don't get some more girls in here sometime soon they won't be able to keep up for much longer. So start thinking about it." She then picks up both girls off the bed

Your mom starts to carry them both out of the room when you speak up "What if I did it... instead of you" Your mom makes a thinking noise as she turns towards your room and deposits both twins onto your bed.

After a bit more of her thinking she says "Well I didn't know you wanted me to also fuck your daughter" she makes a motion that implies she is thinking more "Well I suppose if I tell the lab you were doing this for me they would help out." she turns to leave and says on the way out "Yeah that's a great idea I'll let the lab know so don't keep me waiting too long" and she leaves your room with both twins still asleep on your bed.

You lay on the small bed with both the twins and wrap your arms around them both. You fall asleep quickly and when you awake the twins are now sandwiching you.

Trapped between the twins you look at your device and tap through the images, none of them have cum in them anymore. You then get a message from Jen 'Yo your mom told me that you and your Girlfriend wanted to donate your daughter to your mom. That is so supportive of you, wish I had a son like you. The lab would like to help you out with this so come in today and bring your Girlfriend'

Well you now have a plan for today so you wake the twins "Get dressed we got to go to the lab today" everyone was dressed for breakfast and you notice that Carol was wearing the panties that connect to a Cock Sheath. From the bulge in your mom's pants you can tell she isn't using it so you don't know where it is. Ellie wasn't wearing any panties today though and when your mom told the twins why were going to the lab today she made a point to sit on your lap the entire ride to the lab

Walking into the lab Jen was at the desk again "Oh John you're here!" she smiles at you. Then she looks around a bit and says "Now where's your Girlfriend?" she gets a sly look on her face when Ellie shyly raises her hand "Oh John if I'd have know your mom was fucking your Girlfriend I'd have given you a different gift the other day" She then says to Ellie "Someone will be by to take you to get some upgrades" Jen throws a wink at her as she says that and leads you into the same door your mom disappeared in the other day.

You are led into a room with a conspicuous mirror wall that you know someone is probably watching. Jen puts on a lab coat and pulls out a Cock Sheath quickly replacing the one she is currently using with it and places the old on on the counter "Now get undressed we can't get started with clothes on"

You don't get the option of protesting she just pulls you along and starts undressing you since you didn't start doing it yourself.

You are then led to a small table and she guides you to lay down on it. She ties you in place preventing you from moving around. Then she just waits she tells you she is waiting for a few more people. Then the door opens again and Carol enters now she is naked save for the panties she was wearing earlier and another person wearing a labcoat enters following her.

She is walking weirdly stumbling every few steps and she has a hand over her belly, you see she is grabbing a rather sizable bulge. It is much larger than your mom and when you look at Jen she just winks at you and she pulls the Cock Sheath down a bit letting you catch a glimpse of it before shoving it back up.

Carol stumbles a bit more as you notice that the bulge is higher than before Jen must have shoved it deeper than before.

"Alright Carol go ahead and relieve him, We can't have him releasing during the procedure" Carol aproaches you and looking at your hard dick she just puts a hand between your legs an puts a finger into your backdoor and quickly spins it around and curves it making you cum instantly

Jen speaks up "Oh that was fast, we might have to go for a second time just to be safe". Carol lets out a gasp and when you look at her you can see the bulge moving on her belly, looking at Jen she is sitting down and slowly using the Cock Sheath to rub up and down on her cock. Carol's finger becomes wild and more forceful and you let out another this time painful spurt of cum.

Then she removes her finger and walks over to Jen who pulls the Cock Sheath off of her cock and hands it to Carol. She then walks over to you and tips the Cock Sheath over and pours the cum that Jen put inside of her onto one of her hands and reaches out and smears the cum all over your balls. She then quickly pushes the Cock Sheath over your dick immediately bottoming out inside of the pussy.

Carol doesn't make any sign that she is currently fucking herself on you, but the two quick orgasms have left you pretty drained. Before your hardness disappears from the side the other woman on the room who hasn't done anything yet produces a large needle and quickly injects you in the arm. You can instantly feel the effects of the injection you don't know what it is but you feel a heat spread out from the injection and when the heat retches your dick it becomes painfully hard.

You must have passed out because when you wake up you see Carol sucking on Jen's cock but she pulls off it and angles the cock at you that spurts out hitting you in the face causing you to sputter and your eyes are **** shut. You notice that you feel the cum covering your entire body, just how long have been out of it? Jen speaks up then "Oh John welcome back, don't worry nothing crazy happened. We don't do a lot of tests to improve the production of male organs so this is what the test is for"

You are still trying to prevent the cum from entering your mouth so you don't say anything. Jen wipes your face off allowing you to open your eyes. "So your Girlfriend is getting to upgrades to increase the chances of the baby happening with you. I also added a special feature to your device for this occasion" When you try to get up you notice you are still tied to the table "Can't get up you need to soak for a bit more" Jen tells you. "Don't worry Carol here is helping me keep a constant supply to keep you covered the entire time" and true to the words she spoke she angles Jen's cock at you and it releases a spurt of cum that lands on your chest.

You notice the Cock Sheath discarded to the side with cum leaking out of the now gaping pussy. You are about to say something when another spurt of cum lands on your face and into your open mouth, you spit out the cum as quickly as you can but you can't get rid of the taste that is all you can taste now.

Jen speaks up then "That should be enough, just wait a bit longer now. Ellie was done very quickly. We do a lot of tests on improving the girls so we already knew what to do" You can't see anything as your face is still covered in cum but she continues speaking "I added a feature to your device that will put the woman into a heat it takes a bout 3 days to turn off or once they are pregnant do only activate it when you are planning to impregnate one of them" she tells you to just double tap the button to activate it.

You hear her leave and you are left there to just soak in the cum. For some reason you have been feeling exhausted the entire time and you fall asleep.

When you awaken you are dressed and in your bed at home and you hear the rhythm of your mom's bed banging against the wall.

Leaving your room you realize it is late at night and when you look in you see the twins in a 69 position with your mom thrusting into the one on top as the one on the bottom licks the cum leaking from the pussy. You almost release a yawn and not wanting to be caught you head back to your bed and sleep the rest of the night away after undressing yourself
